Question:

Two angles of a triangle are 20 and 50. What is the third angle?

Keely S.

The three angles of a triangle add up to 180 degrees. Add 20 + 50 and then subtract it from 180 to find the missing angle. 180-70=110 OR 20+ 50+ X = 180 70 + X = 180 X = 180 - 70 X = 110

Question:

20% of what number is 48?

Keely S.

Begin by rewriting the problem with math symbols that the words correspond to. "of" is multiply "what number" is variable x "is" means equals = 20% x X = 48 Change percent to a decimal. Ask me if you do not know how. .20X = 48 Get the X by itself by dividing both sides by .20 x = 240

Question:

Solve for x: 2x+4x=12

Keely S.

Begin by adding the terms with x together. 2x + 4x would add to 6x Then rewrite the equation as: 6x = 12 To solve for x you need to get the x by itself. To do that you need to divide both sides by 6. Then you would get x = 2
